• Intelligent Caching: Both frontend (Tanstack Query) and server-side (Redis) caching will be extensively utilized, including semantic caching, to optimize performance, reduce redundant LLM/API calls, and significantly cut operational costs (targeting 30-70% reduction).
• Rate Limiting: Implemented at all API endpoints to protect against abuse, ensure fair usage, and maintain system stability under varying loads.
• Comprehensive Monitoring & Logging: Integration with cloud monitoring platforms (e.g., AWS CloudWatch, Google Cloud Monitoring) and Langfuse for real-time tracking of agent performance, token consumption, API latency, error rates, and overall system health. Custom alerts will notify administrators of unusual usage spikes or anomalies.
• Admin Dashboard: A custom-built, secure dashboard (part of the FastAPI application) for platform administrators to manage user accounts, agent configurations, monitor task execution, view detailed cost breakdowns, and oversee platform performance.
